There will be times you mess up...but that's okay, as long as you learn from it. So if things go off-track this weekend, just write down "This happened because of this." Now you know what not to do in the future. It's not a failure if don't make the same mistake again.

One thing I saw was a young couple that would continuously read a magazine, no matter what they were doing. So they would be reading on the stationary bike, then wander over to some selectorized equipment (reading all the way over), and continue reading while doing leg extensions, leg presses, etc. Nothing was very intense, of course. But they would consistently do that at every workout.
